IMPACT MATRIX
SYSTEMIC ROLE
SYSTEMIC ROLE: INTERPRETATION
With the next tool, the "impact matrix"
we go from the level of components to
the level of their interactions. For this
purpose the set of variables appears in
a cross-impact matrix where the effect of
every variable upon any other will be
asked for.
During this step, which will be carried
out in three separate groups, you will get
to know your system from a new point of
view.
The resulting 'consensus-matrix' is the
basis for the calculation of the INDEX
OF INFLUENCE of each variable, that
is: between 'active' and 'reactive' on one
hand and between 'critical' and 'buffering'
on the other.
These positions will enter the tool SYS-
TEMIC ROLE, where every variable is
evaluated cybernetically due to its interdependencies.
In this step it is the system
as a whole which distributes the
variables within a net of 50 fields of different
meaning.
According to its pattern of influence,
each variable is sent towards the four
corners of the 'compass' and thus reveals
its cybernetic role. This may be as
a lever (active), a risk factor (critical), a
measuring sensor (reactive), an inert
element (buffering) or any position in
between.
Thereby, the retrievable statements of
this system tool will give you the first
strategic hints. They are based upon
more than 20 years experience with the
evaluation of concrete projects.
